MIT - I wouldn't consider you particularly strong. GMAT is fine, but not stand out for MIT. GPA is good, but you are at a satellite UT campus. Accounting isn't a particularly hard major. Work experience is nice, but not amazing.
UTA - stronger shot. You are in the UT system. You have a 720 which is good for them. You are domestic which is a plus. Lots of internships will look good to UTA.
IMO - Austin is the move.
https://mitsloan.mit.edu/mfin#mit-experienceMIT would help themselves if they accepted more US kids. Their employment stats would go through the roof. For some reason they have a ton of international kids. That's just how they do things. MIT profiles look like amazing GMAT's, T20 UG schools, well known internships at banking, consulting, science, etc. MIT just isn't going to accept good.
A friend of mine went there and his GMAT, work experience, UG GPA and life story was amazing. You can see this in the kids they profile.
